jskos-vue

Introduction ​

What is jskos-vue? ​

jskos-vue is a library for Vue 3 containing components and utilities related to the JSKOS data format and the coli-conc project. It was developed to make it easier to use JSKOS data and the coli-conc infrastructure in front-end projects.

Note that it was specifically developed with the needs of our Cocoda Mapping Tool and BARTOC in mind. So if certain decisions seem odd to you, it is probably because it was needed in one of those projects. Nevertheless feel free to contact us with your questions, suggestions, and use-cases!

Requirements ​

  • Vue 3
  • One of the following:
    • Node.js version >=18
    • A modern browser
  • jskos-tools
    • Needed for ConceptTree, ItemDetails, ItemList, and ItemName.
  • jskos-vue-tabs
    • Needed for ItemDetails.
  • vue-scrollto
    • Needed for ItemSuggest, ConceptTree, ItemDetails, and ItemList.

For a Node.js project, it is recommended to use Vite.

Installation ​

bash
npm install jskos-vue

Usage ​

Globally in a Vue project ​

This adds all of jskos-vue's components globally to your Vue project (src/main.js):

js
import { createApp } from 'vue'
import App from './App.vue'

const app = createApp(App)

import * as JskosVue from "jskos-vue"
app.use(JskosVue)

// Import stylesheet
import "jskos-vue/dist/style.css"

app.mount('#app')

Globally in a Vue project (individual components) ​

This adds individual components (tree-shakable) globally to your Vue project (src/main.js):

js
import { createApp } from 'vue'
import App from './App.vue'

const app = createApp(App)

import { ItemName } from "jskos-vue"
app.use(ItemName)

// Import stylesheet
import "jskos-vue/dist/style.css"

app.mount('#app')

Locally in a Vue project ​

You can also add individual components where needed (e.g. in some SFC, tree-shakable):

js
import { defineComponent } from "vue"
import { ItemName } from "jskos-vue"
// Import stylesheet
import "jskos-vue/dist/style.css"

export default defineComponent({
  // ...
  components: {
    ItemName,
  },
  // ...
})

Browser ​

The library can be used in the browser, for example via jsDelivr.

Fully working HTML example:

html
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Vue App</title>
    <!-- Our library's stylesheet here (adjust version if necessary) -->
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/jskos-vue@0.2/dist/style.css">
  </head>
  <body>
    <div id="app">
      <!-- You can use the components here -->
      <button @click="scroll">Scroll to 25</button>
      <item-list
        ref="itemList"
        style="height: 100px; overflow-y: scroll; border: 1px solid black; margin-top: 20px;"
        :items="Array.from({ length: 50 }, (v, i) => ({ uri: `uri:${i}`, notation: [`${i}`], prefLabel: { en: `Test ${i}` }}))" />
    </div>
    <!-- Vue 3 production build -->
    <script src="https://cdn.jsdelivr.net/npm/vue@3/dist/vue.global.prod.js"></script>
    <!-- Additional libraries (refer to "Requirements" above to see which are needed) -->
    <script src="https://cdn.jsdelivr.net/npm/jskos-tools@1"></script>
    <script src="https://cdn.jsdelivr.net/npm/jskos-vue-tabs"></script>
    <script src="https://cdn.jsdelivr.net/npm/vue-scrollto@2"></script>
    <!-- Our library (adjust version if necessary) -->
    <script src="https://cdn.jsdelivr.net/npm/jskos-vue@0.2/dist/jskos-vue.umd.min.js"></script>
    <script>
      // Here, we are creating an empty Vue app and include the library as a plugin.
      Vue.createApp({
        methods: {
          scroll() {
            this.$refs.itemList.scrollToUri("uri:25")
          }
        },
      }).use(JskosVue).mount("#app")
    </script>
  </body>
</html>

Development ​

Please refer to the GitHub README for development instructions.

Styling Notes ​

Stylesheet ​

In order for the components to work properly, you need to include the library's stylesheet in your project. All the CSS classes and variables are prefixed with jskos-vue, so there should be no conflicts. The stylesheet is available under dist/style.css in the npm package and you can either use import or <style> to include it (see above).

Box Sizing ​

It is recommended to use the following CSS snippet in your applications to make sure box sizing is correctly calculated (more info):

css
html {
  box-sizing: border-box;
}
*, *:before, *:after {
  box-sizing: inherit;
}

This is not included by default because it might break client applications that haven't accounted for this.

CSS Variables ​

Many of the Vue components in jskos-vue use CSS variables, in particular for colors. These can easily be adjusted to match the components to your application. CSS variables are listed in each component's documentation and are defined in shared.css. There are two main ways of changing these variables:

  1. Via CSS :root or class
css
:root {
  --jskos-vue-arrow-color: blue;
}
/* or use a CSS selector that matches the component */
.jskos-vue-arrow {
  --jskos-vue-arrow-color: blue;
}
  1. Via style property
html
<arrow
  direction="right"
  style="--jskos-vue-arrow-color: blue;" />

There are also some global CSS variables that are used by multiple components:

  • --jskos-vue-bgColor - general background color
    • default: white
  • --jskos-vue-highlight-bgColor - highlight background color
    • default: #fdbd5888
  • --jskos-vue-color-lightGrey - light grey color
    • default: #737373

Note that this list is likely going to grow and that defaults can change any time during 0.x.x releases.
